Geochemical analysis for evaluating the paleoweathering, paleoclimate, and depositional environments of the siliciclastic Miocene-Pliocene sequence at Al-Rehaili area, Northern Jeddah, Saudi Arabia

Abstract Geochemical data and their various approaches are useful to evaluate the climatic control on depositional environments. This study aims paleoweathering plaeoclimate condition that have controls environments of Miocene Pliocene siliciclastic sequence at Al-Rehaili area, north Jeddah. To achieve this aim, selected sandstone samples were geochemically (major trace elements analysis) petrographically examined. The results these analyses reveal examined sandstones deposited in non-marine (fluvial/alluvial-lacustrine) suffered from weak intermediate chemical weathering intense physical induration under semi-arid semi-humid conditions.
